To all Loli/0m it may concern Be it known that I, JAMES W. Cocinas, acitizen oi the United States, and resident ot' Philadelphia, county ofPhiladelphia, and

State of Pennsylvania. have invented an Improvement inRivet-Setting-Machines, of which the following description, inconnection with the accompanying drawings, is a specilication, likeletters on the` drawings representing like parts. v

The invention to be hereinafter described relates to rivet settingmachines, and more particularly to that type of such machines torriveting hand bags, suit cases, and the like.

In machines of this general character, the work to be riveted issustained by a rigid work support or post, while the rivet setting forceis applied by a plunger toward the work support' or post to cause therivet to V first pass through the work and then be set.

The character of the rivet setting force is such that the work' supportor post must be rigidly held to withstand the constantlyrecurring` blowsto which it is subjected, and to this end ithas heretofore been proposedto connect the' work support or post directly with the machine frame bybolts or other securing"means, or by casting a. portion ot the worksupport directly with the machine frame or standard. The shorter thework support or post, the more effectually will it withstand the rivetsetting blows with a constant increase in the life of the machine.Certain kinds oi' work, however, require a longl work supporting post orspindle, and this is particularly so in riveting the loottoms; corners,etc., of deep hand-baga'and the like. Other-'kinds oit work do notnecessitate the use of such along work support- ,ing post or spindle, asin riveting ordinary suitcases, or shallow handbags,andwhere this workis to be` done advantage has heretotorelbeen taken' ofthe vfact that awork supporting postor spindle of' less length inight be employed, andasecond machine having such shorter or medium length post or spindle hasbeen provided. In some other classes of work, such as securing thehinges, locks, etc., to hand bags and suit cases, only a very short worksupporting post or spindle is necessary, and since the life of themachine isto an extent dependent upon the length of the work-supportingpost Specification-ot' Letters Patent.

Patented J une 6,1916.

or'spindle and its consequent' rigidity and ability to standup under theriveting blows, a third machine has generally been provided with a shortpost or spindle.- In the factory equipment for setting rivets,thereiore, three machines have usually been provided, each with awork-supporting post or spindle of appropriate length for the specialwork to be done by that machine.

Une oi the purposes of the present invention is to provide a machine ofthe general `character mentioned. with a plurality 01":

work-supporting posts or spindles of appropriate length required for thework of setting rivets ,in hand-bags, trunks, suit aises, and the like,and so combine such plurality of posts or spindles in a single machinethat any one of them may be'placed in operative position relative t0 therivetsetting mechanism.

Another important feature of the present invention consists inassociating the various spindles or posts on a sleeve, the character andlength `of which are such that each spindle or post may be as rigidlysupported for the actionjof the rivet setting mechanism as it' securedor bolted to the machine frame itself.

Still another feature of the invention consists-iii securing each of theseveral posts or spindles ot varying length as required by the work to asingle sleeve having extended bearings on the machine column and capableof rotary movement thereon to bring any one of the posts or spindlesinto operative position according to the character of work tobe done.

Other features ofthe invention will liereina'fter be described inconnection with the accompanying drawings, showing a good practicalembodiment of the invention in its entirety.

In the drawings: Figure 1 is a side-elevation of a. rivetsettinginachine, some of the parts being broken away,- ernbodying thepresent invention; Fig; 2 is a front elevation of the machine shown-inFig. 1; Fig. 3 is a section on line 3-3, Fig'. 1; and Fig. i is asectional detail showing aportion of the rivet setting mechanism.

The machine frame may be 0f any usual or desired forni appropriate forthe hereinafter-described purposes, and as shown, comprises a baseportion 1 from which rises the machine standard 2 surmounted by thegoose-neck 3 for supporting the rivet setting mechanism. The frontportion of the goose- 'curing means, the block 5 may be readily removedfrom the machine frame and with it the rivet setting mechanism. This isoften desirable for purposes, of repair, or change in the operativeconditionaof parts or for the-substitution of different fr-ms of rivetsetting head.

from the chute 7 which communicates with a suitable rotating member 8 towhich the rivets may be supplied through the delivering trough 9. Theshaft 10 carries within thehopper S, suitable rotating means foragitating the rivets, but as these form no essential part of the presentinvention, de-

scription thereof is unnecessary. Secured to the shaft 10 is a ratchetwheel 11 adapted to be actuated for rotating the agitating means withinthe hopper by the pawl 12 mountedv on the arm 13 which isitselfpivotally secured by a detachable pin 14 to the mainoperating arm 15 ofthe rivet setting mechanism. The arm 13 is preferably slotted,` as

at 16, to embrace the shaft 10 and be guided thereby. Mounted forreciprocating movement in the block 5 is the rivet setting plunger 17which is connected at 18 to the stirrup or link 19 secured to the endofthe operating arm 15, substantially as indicated in Figs. l and 4. Theoperating arml is pivotally mounted on brackets rising from thegoose-neck 3, as at 20, the construction being such that upon movementof the operating arm 15 through the means hereinafter to be described,the rivet setting plunger 17 may he reciprocated in the block and theagitating means in the hopper 8 may be suitably rotated.

As the rivets are fed downward in the chute 7, they are to be presentedsingly to the rivet holder which, in the present form of the invention,comprises the head 21, l Fig. 2, carried by the arm 22 mounted forreciprocating movement in the block 5 and normally held in raisedposition by a spring 23. The arm 22 has connected therewith an adjustingscrew 24: whereby to limit the delivered to the holder 21 one at a time,the

chute 7 is provided with a cut-ofi' or slide 25, Fig. 4, which ismounted for movement 'slide in position to transversely ofthe chute andis provided i with an opening, as' usual for the passa of a rivet`therethrough from a position a ve to a position below the said cut-oilor slide. Thefcut-of or slide 25 is normally under the influence-of thes rin 26 which` acts upon the slide or cut-o to old it in the positionindicated in. Fig. 4, whereb it prevents movement of rivets downwar inthe chute. Pivotedto the block 5 at 27 is a slide actuator 28, the upperend 29 of which is in the path of a arm 15. e actuator 28 is providedwith a in 30A mounted on the actuating' leaf spring 31, the end of whichnormally l rests against the end of the slide or cut-off 25 opposite thespring 26, the construction being such that upon operative movement 'Theblock 5 has extending upward therebeing imparted to the arm 15 ashereinbefore explained, the yactuator 28 will be moved upon its pivot 27and the leaf spring 31 thereof wlllcause a yielding movement of theslide 25 to bring the opening of the rmit a rivet in the chute to passto the ower partthereof, as usual.

From the construction thus far described,

it will be noted that by the simple removal of the two screws 6 or otherholding means, the block 5 together with its contained or supportedrivet setting mechanism may be entirely removed from .th'e machine afterlhaving also removed the removable pin 14 which holds the ratchetoperating arm to the actuating arm 15. It will also be noted that theslide is moved in opposite directions by springs 26 and 31, the'spring31 being stiffer or more energetic than the spring 26 so that as theslide 25 moves to permit a rivet to pass down the chute to the holder,its actuation is of a yielding Anature and likewise on its return sothat in case of any obstruction, the slide or pther parts may not beinjured or broken.

As hereinbefore pointed out, different kinds of ivork require differentkinds of work supporting posts or spindles, and it is a recognized factin the art that the spindles must be retained with suiiicient rigidityto Ywithstand the repeated blows delivered thereto by the rivet settingmechanism. This rigidity is mostfillly `secured by a short work suprting post or. spindle on account of the siidrter leverage, and the arthas` recognized this fact by the employ-- ment of such short posts orspind es where the character of the work to he one permitted. Therigidity of the work-supporting spindle is also dependent upon its rigidconnection with the supporting part which,

in the ordinary riveting machine, lspart of the machine frame.

In order that the rivet setting may be carried into clfect upoir thebottom portion of deep hand bags, trunks, and the like, a

long supporting post or spindle is required;
